Unlike the BMI, both the muscle and the fat mass are taken into consideration along with the height and weight to know the Fat Free Mass Index (FFMI). The only difference between the Fat Free Mass Index and the Body Mass Index (BMI) is that the BMI does not take the muscle mass into consideration.
Thus, The Fat Free Mass Index Calculator estimates your FFMI and approximates your values. These values aid in maintaining six-pack abs. This provides a great tool for professionals who are involved in modeling.
